Pressure Seal Gate Valve
Main Features:
The pressure seal valves are designed for service in high temperature and high pressure environments and are widely used in fossil fuel power plants. Compared with bolted bonnet joint valves, it provides absolute reliable sealing of the bonnet joint, making the pressure seal valves more compact, rigid, and cost-effective in maintenance at high temperatures and pressures.
These gate valves are known for their simple structure, reliable performance, and ability to allow slight flexible deformation to compensate for angular deviations on the sealing face during processing, thus improving process performance. In addition, the seat and gate disc sealing surfaces are overlaid with iron-based alloys, cobalt-based alloys, or carbide alloys for long-term durability.
